    The UK issued silver dollars once. They were dated 1804 and considered “bank tokens” as they had less silver than their denomination required at the time. They basically stamped a new design on Spanish colonial 8-real coins and passed them as five shillings.

    The UK had a hard time with coin supply for most of the 1700s until 1816 when they finally downdized many coins.

    ifupdown2 has a 15-character interface name limit, and the systemd predictable interface naming system uses the mac address for usb nics (giving them a 15-character name), so if you try to create a vlan subinterface of a usb nic using the standard interface.vlan naming scheme on a systemd host, it will fail, and you’ll have to set up systemd network link files to rename the base interfaces to something shorter.

      Tell me you had to do real work with Systemd and discovered what a steaming useless pile of millennial shite it is as a whole, without using those words. The only cure for lennart’s cancer is to cut it out.

      Reminds me of the ESP32 ROM dictionary only taking a 15 character limit and simply bugging out silently without any notification whatsoever. Arduino, so easy to use, great for beginners. It has got all the wild goose chases!

      I’m almost sure the backstory to how you gained this knowledge is “i spent hours debugging something, and that 15 chars limit was the problem”

        Yep exactly! Setting up a raspberry pi low-performance computing cluster with secondary usb nics, going slowly insane trying to figure out why the vlan interfaces wouldn’t work when their base interfaces worked just fine, and going down all of the wrong rabbit holes along the way.

        I don’t think so, these numbers are population averages and the relationship probably doesn’t apply at the individual level. Also humans don’t tend to follow this rule as closely due to things like medicine.

    I’m Western esotericism, names have power beyond simply being signifiers for the thing they represent- they embody some part of the thing they represent. The word “fire” contains some intrinsic “fire-ness” but not the whole picture. After all, everyone has different names for the same thing. It is thought that everything has a “true name” that perfectly encapsulates all things about it in their entirety, and this true name could be found by intense study, meditation, or etymology. The Bible pays a lot of attention to names in this way. Adam, the first man, names all the animals. Genesis pays a lot of attention to the names of places, and a lot of stories in Genesis are essentially folk etymologies of locations. God’s own name is of special importance, and its meaning was revealed to Moses by the Burning Bush. Even today Jews believe that even saying God’s name is powerful and dangerous and that only the High Priest would be allowed to say it once every year during Yom Kippur. Jewish folklore says that even this name is merely a part of God’s true name, and that Moses pronounced a longer more complete form of The Name to part the Red Sea, and some systems hold that there are even longer and even more complete forms that have been known to rabbis in the past.

        Yes. God’s name is super interesting because of the extremely strong taboos surrounding saying it, stemming ultimately from the Third of the Ten Commandments (Exodus 20:7)- “Thou shalt not take the name of the LORD they God in vain; for the LORD will not hold him guitless that taketh his name in vain.” Note the emphasis on the name of The LORD, and how the word “LORD” is all caps- this is a sort of censorship of God’s actual name, which goes back to the ancient Greek translations of the Hebrew scriptures. When you see “LORD” in a Bible passage in English, the original passage has God’s name in Hebrew. Jews have historically said the word “Adonai” (meaning Lord) instead of God’s name when reading aloud, and almost all translations follow this and just use the word for “Lord” (Kyrios, Dominus, etc.) instead.

        Anyway, the name is rendered in Hebrew as “” which is roughly equivalent to the letters “YHWH” in the Latin alphabet. Hebrew doesn’t use vowels, and the vowel sounds hsve intentionally not been recorded by scribes. The modern academic reconstruction is “Yahweh” for the pronunciation based on names for people and places that include parts of the name. You may also see “Jehovah” in some contexts which is based on older German scholarship that incorrectly rendered the vowels of the word. The name’s meaning is given to Moses in Exodus 3:14 where Moses asks who he should tell his people to worship and God replies “I AM WHO I AM” “Say this to the people of Israel: I AM has sent me to you” (in Hebrew, I am who I am is Eyeh Asher Eyeh). Modern scholarship agrees that the name has some connection with the word “to be” and means something along the lines of “The Existing One.”

        Myself, I interpret God’s response in the story and the meaning of His name as a declaration of self sufficiency, that God is what exists in His own right, and doesn’t need anything or anyone else to exists. It’s not only a declaration of montheism, but a declaration of supremacy over all of the universe. But yeah, not only does your Bologna have a first name, but God does too if you’re Christian or Jewish.

    There is only one model structure that can be put on the category of small categories for which the weak equivalences coincide with honest equivalences of categories. It’s called the Joyal-Tierney model structure. You can define the suspension of an object in any model category as the homotopy pushout to two terminals, then define an abstract notion of a sphere in any model category by setting the 0-sphere as the coproduct of two terminals and the (n+1)-sphere as the suspension of the n-sphere.

    A small category is a CW-complex if and only if it is a groupoid.

    Not sure if I can call this knowledge since I don’t know if it’s true, but I think I identified a couple of women from the 8th century CE who are mentioned in some Irish annals as actually being the same person. As far as I know there’s next to no discussion of these women on the internet and there are basically no historical records of them, at least. So I guess if I’m right it’s very obscure?

    The women in question are Eithne ingen Bresail Bregh and Eithne ingen Cinadhon (and possibly also the legendary Eithne mother of Tuathal Techtmar)

      This is a really good one. Were they/was she a notable individual? I’m imagining humorously it’s a completely random person.

        It’s about as close to a random person as you can get while still being recorded. They were royalty, but the two real ones get literally a sentence each at max

        • Eithne ingen Bresail Bregh married the king of Tara and is described as “having deserved reward from God for her good works, and for her intense penance for her sins” in one source and “deserved to obtain the heavenly kingdom, having done penance” in the other
        • Eithne ingen Cinadhon was the daughter of a Pictish king and is literally only recorded as having died
        • The legendary Eithne is the daughter of a king of Scotland (mostly Pictish at the time) and crossed the sea to Ireland, where she gave birth to the hero Túathal Techtmar. This is the entirety of her role in the story; a couple of paragraphs in a collection that, in the translation I’m looking at, has 600 pages just for part five

    Reign of Kings, a medieval online PvE survival game had a bug where the 360 rotation camera could be used in 3rd person mode to look inside of walls of other players. You could even access their chests if they built them against the wall (which they all did).

    This meant that you could loot everyone’s bases without even breaking in. The game went through several major updates with this bug still in place. My brother and I used it extensively.

    One day there is a major update and the release notes mention about how they have now finally fixed the “glitch where players items disappear from chests when placed near walls”.

    Real G’s move in silence like lasagna.

    There’s a trick with our loan servicing XML imports. If you pre-encode the property address into a <Comment> tag inside the <CIF> section, the system auto-fills it in three different screens, even though none of them actually pull from that tag offcially. I don’t know why it works, just that it does. Doesn’t really save me more than about thirty seconds but when you’re boarding dozens of loans per week, it can add up.

    From an old edition of the Pilot’s Handbook of Aeronautical Knowledge:

    An airplane’s tire will hydroplane at a speed in knots equal to 9 times the square root of the tire pressure in PSI. So if your tires are inflated to 36 PSI, sq.rt 36 = 6 * 9 = 54 knots. If there is standing water on the runway, you will have no braking authority or steering control from the wheels, you will have to maintain control of the aircraft with the flight controls, and you cannot rely on short field stopping figures from the POH if it requires applying brakes above 54 knots.

    I got that out of the 2003 edition; I don’t know if it’s in the current issue.

    The most efficient base for a number system is e.

    We use base 10 with 0-9 digits and each position is a ten’s place, and the efficiency being measured is the product of the number of digits and the length of digits needed to represent a number in a given range of values. So if we used base 2 binary instead of base 10 decimal we only need to remember 2 digits 0-1, but to represent most numbers we’ll need more digits, 11 in base 10 is 1011 in base 2. On the other side we could use hexadecimal to write shorter numbers like 11 is B, but need to use more digits, 0-F digits where A-F are the 10-15 digits.

    If you try to plot a function that minimizes the efficiency the minimum is at e. So you’d have digits 0-2 and e would be written as 10 since each position is an e’s place.

      Briefly looked into it, and found an old stack post that said we know at least one is irrational. It would be pretty interesting if the other were rational.
